Patch from gentoo-musl, implementation is from ISC (all known implementations are from ISC as far as I can tell).

  • Tested using sandboxing (nix.useSandbox on NixOS, or option build-use-sandbox in nix.conf on non-NixOS)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nox --run "nox-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Fits CONTRIBUTING.md.

Sorry, something went wrong.

a) For `nixos-rebuild` you can set
  { nixpkgs.config.allowBroken = true; }
in configuration.nix to override this.

b) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
  { allowBroken = true; }
to ~/.config/nixpkgs/config.nix.

You should also point out that this code is coming from glibc. This safes people from reviewing the code below.

Or maybe just fetch it: https://sourceware.org/git/?p=glibc.git;a=blob_plain;f=resolv/base64.c;hb=2d813d7b77ba8341a0a982d74bb59f5a0d775784

I don't believe this code originated with glibc. Also, note the OpenBSD comment header. This used to be in the OpenBSD tree, not sure of history before that. Good call re:fetching though-- the current version in glibc is still liberally licensed so might be the way to go.

Appears they're from BIND? https://sourceware.org/git/?p=glibc.git;a=blob;f=resolv/README;h=514e9bb617e710f16126c1474561965a2b35653d;hb=HEAD#l104

Ok. Maybe we can assume we never need to touch base64.c because the implementation should not change except for includes.

The bind link would be still a nice hint in case somebody needs to update it though.

Fetching it is a good idea--looks like the gentoo-musl project's patch is fetch-friendly (the alpine one was close but conflicted re:Makefile which is why I had a local copy).

I'll add BIND link too.

netcat-openbsd: fix w/musl by providing b64_ntop
5e3e3e9 
It seems many projects have copies of this code--
and AFAICT all are derived from ISC's BIND[2]
although it does not appear present in recent versions.

This is a curious function as it is not documented
nor part of any standard[1].

[2] for example, glibc's copy:
